Answer: V = 33.9 L

Explanation: We will use Charles Law to solve for the new volume.

Charles Law is expressed in the following formula. Temperatures must be converted in Kelvin.

V1 / T1 = V2 / T2 then derive for V2

V2 = V1 T2 / T1

= 35 L ( 308 K ) / 318 K

= 33.9 L

Waves transport water in the deep ocean toward the coastlines. True or false
ASHA 777 [7]

Answer:

Most likely true

Explanation:

because the speed of all ocean waves is controlled by gravity, wavelength, and water depth. ... Waves moving through water deeper than half their wavelength are known as deep-water waves. On the other hand, the orbits of water molecules in waves moving through shallow water are flattened by the proximity of the sea surface bottom.

29.0g silver combine completely with 4.30g of sulfur to form a compound. what is the percent composition of this compound?
Deffense [45]

Answer:

Percentage of silver and sulphur in the compound  is 87.08% and 12.91%  respectively

Explanation:

Given:

Amount of silver = 29.0 g

Amount of sulphur= 4.30 g

To find:

Percent composition of the compound=?

Solution:

\text { percent of compound }=\frac{\text { amount of element }}{\text { Total Molecule Mass }} \times 100

Total Molecule mass = amount of silver + amount of sulphur

Total Molecule mass = 29+4.3  

Total Molecule mass = 33.3g

Percentage of silver:

\text { Percentage of silver }=\frac{\text { amount of silver }}{\text { Total Molecule Mass }} \times 100

=>\frac{29.0}{33.3}\times100

=>0.8708 \times100

=> 87.08%

Percentage of silver:

\text { Percentage of silver }=\frac{\text {amount of suplhur}}{\text { Total Molecule Mass }} \times 100

=>\frac{4.30}{33.3}\times 100

=>0.1291\times 100

=> 12.91%
